"Quantum" may seem like a useless buzzword, but quantum computing is a real thing, and it's actually understandable even if ...

Quantum computing may one day outperform classical machines in solving certain complex problems, but when and how this “quantum advantage” emerges has remained unclear. Now, researchers from Kyoto ...

Quantum computing is one of those technologies where real-world applications always seem to lie just over the horizon. The next big thing is announced before quickly becoming a forgotten article from ...

On May 7, 1981, influential physicist Richard Feynman gave a keynote speech at Caltech. Feynman opened his talk by politely rejecting the very notion of a keynote speech, instead saying that he had ...

Chicago has quickly emerged as a hub for quantum computing, with the state of Illinois and technology companies pouring millions of dollars into developing a campus to build the world’s first ...

Paris-based quantum computing startup Alice & Bob has announced a stunning breakthrough in quantum computing: its qubits can now resist bit-flip errors for more than an hour. That’s four times longer ...

IonQ and IBM are among those building quantum computers -- a new frontier. Since it went public in 2021, IonQ has approximately doubled its sales each year. IBM's established businesses allow it to ...

China is investing heavily in quantum computing, and the race is on for giants like Baidu, Alibaba, and Tencent. Baidu is focusing on using it for AI.

As a result, IonQ's stock performance will likely be tied to the market's appetite for risk. If the market becomes more conservative in 2026, quantum computing companies will likely struggle, unless ...

D-Wave, IonQ, and Rigetti use different approaches to build quantum computers. All three companies are unprofitable but are generating sales from their quantum systems. The odds are stacked against ...
